Y=2 when x=8 & y=-3 when x=1

Natasha_Volkova [10]

Y=k/x is inverse

y=2
x=8
2=k/8
times 8
16=k
the equation is
y=16/x

second

y=k/x
-3=k/1
-3=k

the equation is y=-3/x

they are
for y=2, x=8 it is y=16/x
and for y-3, x=1 it is y=-3/x

Trigonometry

Alchen [17]

The area of the triangle PQR is 17.6 square units.

Explanation:

Given that the sides of the triangle are PQ = 12 and PR = 3 and $m\angle P = 78^{\circ}$

We need to determine the area of the triangle PQR

Area of the triangle:

The area of the triangle can be determined using the formula,

$\text {Area}=\frac{1}{2} qr \sin P$

Substituting the values, we get,

$\text {Area}=\frac{1}{2}(12)(3) \sin 78$

Simplifying, we have,

$\text {Area}=\frac{1}{2}(36)(0.98)$

Multiplying the terms, we have,

$\text {Area}=\frac{35.28}{2}$

Dividing, we get,

$\text {Area}=17.64$

Rounding off to the nearest tenth, we have,

$Area=17.6$

Thus, the area of the triangle PQR is 17.6 square units.
